i To all whom t may concern.'

Be it known tlietl' Amin V. PAQnnfrTn, a. resident of Chicago; in the county of Cook and State of illinois, have invented certain newf and. useful improvements in Solderingirons, of which the following is a full, clear,

Aand exact description;

' vided .with ineens et its outlet-terminal for cansingthe air end ges to mingle und for directing the flame into the soldering-point.

*still further object of the invention is to provide an improved detachable connecion or'seouring the Vpoint toits supporting tube to facilitate removal or replacement of the bit. l

The vinvention consists 1n the severa-l novel .features hereinafter set forth and more par tion of e solderingiron nernbodying the in-l vention. F ig. 2 is a, central longitudinal section. Fig. 3 is a. section taken on line 3--3 of Fig. 2. Fig. section teken 'on line f 4-4 of Fig; 2. l The improved soldering 4ironcomprises a l vhandle 8; usually mede of wood, 'e ges pipe 15 is formed and longitudinally extending A provided between the point 'andthe tube 22.

9, extending longitudinally through the handle, e shut-off cock l0 connected to one end of pipe 9 'and adapted to be' connected to e tlenibletube 1l from a 'suitable sourceof ges supply, and e coupling member 12..

which is securedby screwthreed to one end of pipe 9. A nozzle 14 is secured to the coupling12, an'opening l5l being formed through-said member to conduct ges from Coupling 12 comprises a ring 16, a. ringvl., in which opening connecting-ribs 18 between said rings. mixing-tube 19 is secured in ring 16 by a screw 20. Nozzle lli is smaller in cross-sec--" tional aree'thantube wend extends ,entirely across the opening between rings-1o endl? through which an' enters the mixing tube e'ectively .heet the point.

end around the nozzle. By thus extending the 'nozzle entirely across the opening between the rings and into the mixing-tube,- the gas delivered into the mixing-tube drawsthe' air into 'seid tube through the space between j the nozzle andx the mixing-tube, so that the air undd gas will be well mixed in the tube to minimize back-firing' j* which muy injure thehand of the operator. In practice, the operator sometimes places' his hund around the coupling 12 end the handle, and if the llame back-fires et suoli' time, there `is danger of injuring his hand. This construction has been found to eiec? tively minimize beck'firing. l A soldering-point 2l is secured to je burner-tube 22, having'holes-QS thereinfor the, esca-pe o the .products of combustion.

TheV inner end of tube 22 is secured to a col ler 24 Whichi's adjustebly securedoy e screw 25 to the mixing-tube 19. Coller 24 has lugs 26 fitting in the tube 22 und air-openings 27 are formed between said lugs. Afsocket or recess 28 is formed in the soldering-point toA permit the tierno topass' into and to more By adjusting the point to or from the flame, heating of the'irOn Vmay be regulated. Sina-l1 outlets .40

for the products of combustion ereformed in the pontv21. y

rfthe 'discharge-terminal of mixing tube 19 is formed with inwardly end forwardly extending tongues 30. These tongues serveto `further iniX the air and gas before reaching the point of combustion and tend to' direct the vtienne toward the point.

Tube is formed of thin or sheet metalv to avoid eXcessive weight, 'end'ris :perforated all over es at 23. By forming this tube of sheet metal, it does not act toceonduet much beet tocoller 24 vso thetthe iron may be .used continuouslyl without heating the hen- L dle. n sonecuses, it is `desiredile to use points, which are usually made of'copper, of differ# ent 'shapes for' dilerent kinds of work' and to' facilitate changing o the points, and to provide a joint which will notice aected by ico'y heat, a detachable interlockingl connection isl This connection consists of studs 31 secured ably lool:l the point and tube l22 together.

Portions 3'olftlee slots 'are angled so as to act as cams which will force the shoulder 3i on the point against the outer end of tube 22. Obviously, the point may be removed from the tube Q2 by partial relative rotation which is simple in construction, economical in operation and in which there is no danger of back-firing at the air inlets to the mixing tubeV The invention is not to be understood as restricted to the details set forth since these may be modiied within the scope of the appended claims without departing from the spirit and scope of the invention.

Having thus described the` invention, what l claim as new and desire to secure by Let` ters Patent, is: Y

1. ln a gas-heated soldering iron, the combination of a lhandle having a gas-pipe therein, a mixing tube in separated relation from the handle, a coupling between the handle and the mixing tube having an air inlet and having one of its ends connected to said pipe and the other to said tube therein, a nozzle connected to one end of said coupling and extending entirely across said inlet and terminating in the mixing tube, and a soldering point connected to said tube.

2. ln a gas-heated soldering iron, the combination of a handle having a gas-pipe therein, a mixing tube in separated relation from the handle, a coupling between the handle and the mixing tube comprising a ring secured to the gas-pipe, a ring in which the mixing tube is secured, and llongitudinal connecting ribs between the rings, a nozzle connected to the ring which is secured to the gas-pipe, and extending entirely across the space between said rings and into the mixing tube, and a soldering point connected to said tube,

3, l'n a gas-heated soldering iron, the combination ot' a handle, a gas-supply pipe connected to the handle, a nozzle connected to said supply, a mixing tube supported to receive fluid from said nozzle, having inwardly extending tongues at its discharge terminal, and a solderingpcint connected to 4the nnxing-tube.

e. In a gas-heated soldering iron, the

receive fluid from said nozzle, having inwardly extending tongues at its discharge terminal, a. perforated tube removably secured to the mixing-tube, and a soldering point secured to the perforated tube. Y

6.1m a gas-heated soldering iron, the combination .of a handle, a gas-supply pipe connected to the handle, a nozzle connected to said supply, a mixing tube supported to receive fluid from said nozzle, a coupling between the handle and said mixing tube having an air inlet therein, a collar adjustably secured tothe mixing tube, a pertorated sheet metal burner tube, the collar having lugs with openings therebetween to which one end oit' the burner tube is secured, and a soldering point secured to the other end of the burner tube.
